The much-needed precipitation moistened vegetation and gave a little boost to reservoir storage, but the biggest benefit will be the water savings this week from residents turning off their sprinklers.

A widespread, one-week irrigation hiatus could save the county 2,000 acre-feet of water, which is enough to serve 4,000 families for a year, according to the San Diego County Water Authority.

Up north in the Sierra Nevada, where San Diego gets 20 percent of its water supply, the storm brought up to 4 feet of snow and increased the overall state snowpack by 6 percent.

"Statewide, we’re still in a drought, and it’s a very serious drought, and the impacts are very significant," said Lesley Dobalian, water resources specialist with San Diego County Water Authority.

"So that is still very low," Dobalian said. "A statewide snowpack at that level really is not what we would expect or want at this time of year, and in fact, statewide reservoirs are also still very low compared to average."
